PAPER-BAG MACHINE.

SPECIFICATION forming part of Letters Patent No. 482,170, datedSeptember 6, 1892.

Application filed March 17, 1892. Serial No. 425,244. (No model.)

To 00 whom it may concern.-

Be it known that I, ALBERT C. GETTEN, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Paper Bag Machines, ofwhich I do declare the following to be a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My present invention has relation more particularly to that class ofpaper-bag machines designed for forming square-bottom bags; and itsobject is to simplify and improve the mechanism whereby the creasing andpasting of the bottom portion of the bag is effected.

To this end my invention consists in the novel features of constructionhereinafter described, illustrated in the accompanying drawings, andparticularly pointed out in the claims at the end of this specification.Figure 1 is a plan view of the pasting and creasing rolls and adjacentparts. Fig. 2 is a view in vertical transverse section through thepasting and creasing rolls. Fig. 3 is a detail plan view of the pastingand creasing rolls. Fig. 4: is a view in central transverse sectionthrough Fig. 3. Fig. 5 is a viewin side elevation, showing in full linesthe shape of the bag-blank as it enters the pasting and creasing rolls.

A designates a portion of the .main frame of the machine. In the upperpart of the main frame are journaled the pasting and creasing rolls Band B, these rolls being geared together to insure their unisonmovement. The roll B may for convenience be termed the male roll, sincethis roll carries the male creaser-blades and the paste-pads, while theroll B maybe termed the female roll, as this roll serves to carry thefemale or groove creaser plates or channels and is cut away to permittheproper action of the paste- The creaserblades 0 and C are set withinchannels extending across the face of the roll B, and the base of eachof these blades 0 and O is furnished with an extension 0, whereby it isattached to the roll. The creaser-blade G has its extension 0 providedwith slots 0 to admit the set-screws 0 whereby the blade is attached tothe roll, the object of this arrangement being to permit the blade to beadjusted in order to vary the distance between the creases made in thebag-blank to permit different sizes of bag-blanks to be creased, as willhereinafter more fully appear.

The female or grooved creaser-plates D and D consist each of parallelplates set at sufficient distance apart to receive the creaserblades 0O, and the base of each of these female creaser-plates is furnished withan ex: tension (Z, whereby it is attached in its corresponding grooveextending across the face of the roll B. The grooved creaser plate orchannel D has its base 01 provided with slots d to admit the set-screws(1 this arrangement permitting an adjustment of the plate D,corresponding with the adjustment of the male creaser-blade C and forlike purpose.

Upon the bag-blank shown in Fig. 5 of the drawings the position in whichthe paste is to be applied is indicated by the stippled lines 2,3, and4, and in order to lay the paste upon the side flaps and one of the endflaps 51 ofthe bag bottom at the points indicated the male roll B isprovided with two parallel paste-padsj E and E, which distribute thepaste upon the side flaps of the bag bottom and with the paste-pad Ewhich serves to distribute the paste upon the end flap of the bag bottomat the points 3 and 4, Figs. 3 and 5. The female roll B has itsperiphery formed with grooves b at'points opposite the pastepads E, sothat no hard backing or resistance will be'offered to the opposite sideof the bagblank as the paste-pads E apply the paste thereto, and forlike reason the female roll is provided with the transverse groove 1) ata pointcorresponding in location to the pastepad E", which serves toapply the paste to the end flap of the bag bottom. The paste-pads E andE will be supplied with paste by a suitable paste-roller E working in atrough E these pads being higher than the blades C C, which escapecontact with the roller E As the bag-blank before its delivery to therolls B will have been folded by suitable mechanism into the shape shownby Fig. 5 and with its sides provided with the usual bellows fold, andas it is desirable to avoid the compression of the bag-blank upon itsouter edges and upon the lines 5 5 of the bellows fold, I form the rollsB and B with the raised portions b adapted to bear upon the bag-blankbetween the lines 5 5 (see Figs. 1 and 2) and the outer edges of theblank, and these raised portions follow the creaser-blade G and thegrooved creaser-plate D, so as to insure the feed of the bag-blankthrough the rolls B B after the blank has left the bight of thecreaser-blade and plate 0 and D.

From the foregoing description it will be seen that if a bag-blankpreviously folded to the shape shown in Fig. 5 of the drawings isintroduced between the rolls B B at a time when the creaser-blades G andgrooved plate D are in the position in which the blade 0 and the plate Doccupy in Fig. 2 of the drawings and motion is imparted to these rolls,the creaser-blade C will contact with the bag-blank at thepointindicated by the dotted line 6 of the drawings, Fig. 5, and willforce the blank into the grooved creaser-plate D, thereby creasing theblank upon such lines, and as the rolls B B continue to revolve thebag-blank will be carried forward until the blade 0 forces the blankinto the grooved plate D and forms a second crease upon the line 7 ofthe bagblank, as seen in Fig. 5. Previous, however,

to the creasing of the bag-blank upon the line 6 by the blade 0' andgrooved plate D the paste-pad E will serve to apply paste at the points3 and 4 upon the end flap 51 of the blank, and as the blank is beingdrawn through the rolls B B the paste-pads E and E will apply the pasteto the side flaps of the bag-blanks and intermediate the lines 6 and 7,upon which the blank will be creased. Hence it will be seen that by thepassage of the bag-blank through the single set of combined creasing andpasting rolls B and B the bagblank will be at once creased upon theproper lines for subsequent folding and will have paste applied atproper points to insure the retention of the bottom flaps when folded.When bags of larger size and consquently having wider bottoms are to beformed, the adjustable creaser-blade C and the adjustable creaser-plateD will be moved backward a corresponding distance to increase the widthbetween the lines of creases 6 and 7 to be formed on the blank. Thecreaser-blades C and O are provided with transverse slots 0 to preventtheir contact with the doffer-fingers F.

My invention resides in the features of novelty hereinafter defined inthe claims, and it is manifest that the invention can be employed,either in whole or in part, in connection with various types ofpaper-bag machines.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a paper-bag machine, the improved means for creasing thebag-blank, which consists of a pair of rolls, one of which rolls isprovided with two creasing-blades, one of said blades being adjustablearound the periphery of the roll to enable it to be shifted with respectto the other blade and the other of which rolls is provided with twogrooved creasing plates or channels, one of which is adjustable aroundthe periphery of the roll to permit it to be shifted with respect to theother, whereby the distance between the creased lines of the bag may bevaried as desired. substantially as described.

2. In a paper-bag machine, the improved means for creasing and pastingthe bag-blank, which consists of a pair of rolls, one of which rolls isprovided with paste-padsand with two creasing-blades, one of said bladesbeing adj ustable around the periphery of the roll to enable it to beshifted with respect, to the other blade and the other of which rolls isprovided with two grooved creasing plates or channels, one of which isadjustable around the periphery of the roll to permit it to be shiftedwith respect to the other, whereby the distance between the creasedlines of the bag may be varied as desired, substantially as described.
